What is the function of UCPI?
A)Allows more white fat to accumulate in adipose tissue.
B)Reduces the amount of hydrogens available to make ATP.
C)Provides more body heat from oxidation of fatty acids.
D)Both reduces the amount of hydrogens available to make ATP and provides more body heat from oxidation of fatty acids.

Question

Quizplus · Accepted Answer

UCPI (uncoupling protein-1) reduces the amount of hydrogens available to make ATP by uncoupling the proton gradient from oxidative phosphorylation. Instead, it allows the energy to be released as heat, providing more body heat from oxidation of fatty acids. This function is important for thermogenesis and maintaining body temperature in certain animals and humans, such as newborns and hibernating animals. Therefore, both choices are correct. Option A is incorrect as UCPI promotes the transformation of white fat into brown fat, leading to increased energy expenditure rather than accumulation.
